A successful relationship is based upon mutual agreement, not upon obedience to orders. If you want someone to obey your word, get a pet dog. They can be trained to obey. Girlfriends are another matter. As for her parents criticism of you, you can certainly discuss it with your girlfriend. The criticism either is valid or it isn't. I personally have no way of knowing. Even if the criticism is valid that doesn't mean that your relationship must fail. Perhaps there is something about you that can be improved.
